sh

"sh" stands for Shell, which is a command line interpreter for Unix-based operating systems. It is one of the most commonly used command line tools and serves as the default shell for many operating systems. The "sh" command allows users to interact with the operating system by executing commands and scripts. It provides a command line environment to execute and control various tasks on the computer. Users can navigate through directories, create, delete, and manipulate files and directories using "sh" commands. It supports various features such as piping, input/output redirection, variables, loops, conditional statements, and functions. "sh" can execute both built-in commands and external programs installed on the system. It supports scripting, allowing users to write and execute scripts that automate tasks and perform complex operations. The behavior of the "sh" command can vary depending on the specific shell implementation. Common shell implementations include Bash (Bourne Again Shell), Dash (Debian Almquist Shell), and KornShell.
